If you test positive for TB, the provider will have you scheduled for a chest X-Ray to evaluate whether or not the TB is latent or active.
If the TB is latent, you will be cleared once our office receives a copy of your chest X-Ray results. If the TB is active, you will need to start treatment immediately.

Does Sea Mar pay for treatment for volunteers/interns/externs with positive TB tests?

This is situational. If you are a current Sea Mar volunteer who has already been cleared, and you test positive for TB at your 6 month checkup, Sea Mar will pay for the cost of your treatment.
However, if you have not volunteered with us before and are in the process of applying, Sea Mar will not cover the cost of treatment should you test positive for TB.
